If Back to the Future 4 ever becomes a reality, the plot should feature President-elect Donald Trump on the campaign trail. Like Marty McFly and Emmett Brown, Trump spent an inordinate amount of time inserting himself in the past, crafting speculative fiction along the way.
In traditional speculative fiction, the author asks the "what if" question. In The Man in the High Castle, Philip Dick asked, "What if the Axis Powers not only won World War II but also occupied the United States?" Stephen King's 11/22/63 asked, "What if somebody killed Lee Harvey Oswald before he could kill JFK?" In The Plot Against America, Philip Roth asked, "What if Charles Lindbergh was president instead of FDR?"
